A box girder bridge, or box section bridge, is a bridge in which the main beams comprise girders in the shape of a hollow box. The box girder normally comprises prestressed concrete, structural steel, or a composite of steel and reinforced concrete. The box is typically rectangular or trapezoidal in cross-section. Box girder bridges are commonly used for highway flyovers and for modern elevate.Three steel structural types were evaluated: 1) plate girders with integral pier caps, as shown in Figures 2 and 3, 2) a single steel box girder, and 3) twin steel box girders, as shown in Figure .

Box girders are used for footbridges curved in plan, bridges with longer spans and cable-stayed bridges with a single plane of stays. All-steel construction is typically used, for lightness. A . Box girders have several favorable characteristics that make their use desirable for spans of about 120 ft and up. Structural steel is employed at high efficiency, because a high percentage can be placed in wide flanges .

The continuous steel box girder is one of the common forms of bridge super-structure. A new type of steel box girder is proposed in this paper (Fig. 1, Fig. 2).The distance between the two webs is narrower than that of the conventional steel box girder and hence we call it a the narrow-width steel box girder.Box girders are usually considered for footbridges only for spans over about 30m, and most box girder footbridges adopt an all-steel configuration. The advantage in using an all-steel configuration is that the whole cross section, including parapets, can be fabricated at the works for delivery and erection in complete spans; the weight of such spans is modest and easily .On a narrow box steel girder bridge, the narrow web distance resulted in a small flange width, so the flange thickness needs to be increased. This allowed the number of longitudinal ribs to be reduced. Fig.3 shows the required number of longitudinal rib with respect to relation between web distance and flange cross section area.Designers Guide to Box Girder Bridges Bethlehem .

The CSW box girder bridge is a new type of girder bridge that was developed in the last century and is widely used in many types of large, medium, and small bridges owing to its various advantages [] (presented in Figure 1.A CSW box girder and its structural parameters are presented in Figure 2, which shows the CSW (where a w, b w, c w, d w, θ w, h w, L w, and t w . Multi-beam box girder bridges have been applied widely throughout the world for many years. . in adhesion/cohesion strength and shear strength, and it especially gives good mobility to grout, conveniently, in the narrow gaps between the box girders. To reduce the amount of carbon-A/-B glue, the steel plates are embedded in the shear key and .
For a composite box girder bridge with corrugated steel webs, replacing a concrete web with a steel web in a composite box girder with corrugated steel webs can effectively reduce the weight of the structure, which will inevitably lead to an increase in the ratio of live load to dead load. Therefore, the dynamic response generated by the live .
The narrow-width steel box girder is an important type of steel–concrete composite bridge structure, which is usually composed of reinforced concrete wing plates, narrow steel boxes partially injected with concrete, and shear connectors that promote shear force transfer. The utilization of narrow-width steel box girders, augmented by partially filled concrete, .
Recently there has been an increase in the use of ‘open-top’ boxes for the creation of composite box girder bridges. Typically, they are employed where the span is in excess of about 50 m and a pair of trapezoidal sections are used with a common deck slab, as shown in Figure 1. The open boxes are erected first and the slab is then cast in situ.DOI: 10.1016/j.jcsr.2023.108380 Corpus ID: 266337629; Fatigue study on improved composite box girder bridge with corrugated steel webs @article{Ji2024FatigueSO, title={Fatigue study on improved composite box girder bridge with corrugated steel webs}, author={Weining Ji and Qian Bai and Wei Wang and Jieqin Li}, journal={Journal of Constructional Steel Research}, . “Investigation of vortex-induced vibration of a suspension bridge with two separated steel box girders based on field measurements.” Eng.

and torsional loading of both single box girders and mul tiple interconnected box girders. To establish the dimensions of the scale-model struc tures, the geometries of a series of prototype steel box-girder bridges provided by the Canadian Steel In dustries Construction Council were examined; typical In this paper, a beam-truss model is introduced for the design analysis of composite box-girder bridges. An integrated research program for beam-truss models, including modeling implementation, analysis, and application, has been performed to exploit this powerful research and design tool. The integration of box girders with corrugated steel webs (CSWs) and an extradosed cable-stayed design gives rise to an innovative and distinctive bridge design, recognized as the extradosed cable-stayed bridge with CSWs. The synergistic integration of the technical benefits facilitates expanding the maximum span and enhancing the adaptability of this structural .
In November 1971 a steel box-girder bridge across the River Rhine near Koblenz in Germany collapsed killing 12 people. Investigating the disasters The British government responded by setting up the Merrison Committee of Inquiry. It was tasked with investigating the design and construction methods of box-girder bridges. It was also asked to make .2.2 Plate Girder Bridges Due in large part to their simplicity and efficiency, plate girder bridges are the most common type of steel bridge. Over time, different types of plate girder bridges have been used, but in modern times, composite, multi-girder bridges have been, by far, the most common type of plate girder bridge configuration.
